The unstoppable verbal and physical tics of Tourette's Syndrome leads to "amazing conversations", according to Jess Thom, who has the condition.
She told Today presenter James Naughtie how her website Touretteshero.com aims to celebrate the creativity and humour of Tourette's.
Her condition means she repeats certain words and phrases involuntarily - particularly the word "biscuit"- but she explained that it can change over the course of a person's life and even over the course of a day.
She said that it only about 10% of people with Tourette's have tics involving swearing, although this is often associated with the condition.
